Phenotypic characterization of different A. thaliana genotypes. a,b) Systemic colonization of a) Ler, Bur and two NILs differing in the vec1 region (experiment 6; one-way ANOVA and post-hoc Tukey test, p < 0.05, n = 6-7), and b) two genotypes differing only in Erecta function (experiment 5, t-test, p < 0.05, n = 6). c,d) Resistance to V. longisporum-induced stunting expressed as performance height in c) an experiment performed in winter (experiment 1, t-test, p < 0.05, n = 6) and d) an experiment performed in spring (experiment 2, t-test, p < 0.05, n = 6). e) Proportion of chlorotic rosette leaves in Bur (squares) and Ler (circles) after V. longisporum-inoculation (closed symbols) and mock-inoculation (open symbols) during the course of a growth chamber experiment. Vertical bars denote standard deviations. Ecotypes and treatments differed significantly from 6 dpi on (p < 0.05; t-test; n = 41 for Ler mock, n = 38 for Ler V. longisporum, n = 60 for Bur mock, n = 58 for Bur V. longisporum).
